PRODUCT OVERVIEW
Pneumatic three-way internal thread ball valve is suitable for pure pipelines such as food, beverage, medicine and chemical industry, as well as pipelines such as industrial environmental protection, water treatment, high-rise buildings, water supply and drainage. It can be divided into "L-type pneumatic internal thread ball valve" and "T-type pneumatic thread ball valve". L-type is suitable for the flow direction switching of media, which can connect two channels perpendicular to each other. T-type is suitable for the diversion, confluence or flow direction switching of media. The double-layer valve stem packing meets the German leakage test requirements. After the system pressure is relieved, it can be inspected and repaired without removing the whole valve body. Any port of the valve can be used as an inlet without leakage, and L-shaped or T-shaped channels can be made according to the working conditions. The pneumatic internal thread ball valve is easy to install.
PRODUCT FEATURES
1. Compact structure, quick opening and closing, smooth flow channel and small fluid resistance.
2. The sealing performance is good, and the elastic deformation of polytetrafluoroethylene, the material of four side valve seat, is used to realize leak free sealing.
3. One valve has multiple functions. Any port can be used as the inlet without leakage. The tee can be made into either L-shaped port or T-shaped port.
4. The maintenance is convenient. After the system is depressurized, the inspection and maintenance can be carried out without removing the whole valve body.
